Keeping the focus on customer racing during the 2010 motorsport season, the new Porsche 911 GT3 R comes delivered to customers ready-to-race and replaces the 911 GT3 Cup S in Porsche Motorsports’ model range. The 911 GT3 R will be raced in [those] series based on international FIA GT3 regulations. In developing the vehicle, the emphasis was placed on improving driveability and making handling easier. The 911 GT3 R features a four-liter six-cylinder boxer engine delivering 480 hp (353 kW). A six-speed sequential gearbox transmits the power to the rear axle. The new 911 GT3 R celebrated its world debut on 14th January 2010 at the Racing Car Show Autosport International in Birmingham (Great Britain).
“Since we first announced our intention to launch the 911 GT3 R, demand has been huge,” says Uwe Brettel, Head of Motorsport Sales. “The number of GT3 R vehicles we had planned for 2010 is almost sold out.” From spring 2010, customer teams around the world will receive their new vehicles. The basic price is 279,000 Euro plus national VAT.
The development of the 1,200 kg lightweight 911 GT3 R is based on the Porsche 911 GT3 Cup presented in September 2009 for one-make cup racing. Thanks to a 0.2-liter increase in engine capacity, the GT3 R delivers 30 hp more than its Cup predecessor. Both race vehicles are based on the extra-wide body of the street-legal 911 GT3 RS.
An anti-lock brake system (ABS), traction control and an e-gas with “throttle-blip” function help pilots familiarize themselves quicker to the new GT3 race vehicle compared to its predecessor, also making it easier for ambitious amateur racers to get used to the car. The flared wheel arches front and rear show the wider track compared to the previous model. The underbody of the vehicle is completely covered and features a rear diffuser. Compared to the forerunner model, the adjustment range of the rear wing has been increased.
The highly developed race suspension can be extensively adjusted: At the front are height-adjustable McPherson struts with variable SACHS two-way shock absorbers and double coil springs (main and auxiliary). At the rear, the GT3 R features a rigidly mounted sub-frame with a height-adjustable multi-arm axle, as well as adjustable SACHS two-way shock absorbers and double coil springs.
